What P0200 means
P0200 is the injector circuit fault without a cylinder assignment. The large US manufacturers do not use it – GM and Ford report injector faults per cylinder (P0201 ff) or as faults of the shared injector supply (P062D/P062E, P2146 ff). Saab documents it on the 3.0 V6 diesel of the 9-5, whose injectors are driven by a separate power stage behind the glovebox: there P0200 means an electrical fault in that power stage or its wiring, and the engine is shut down. Generally the cause lies in something all injectors share – supply, fuse, relay, ground or driver stage – so several cylinders are affected at once. CARB does not require separate codes for each kind of circuit fault.
P0200 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0200
- Check engine light on
- Engine does not start or shuts down
- Severe misfire on several cylinders
- Limp mode, loss of power
Common causes of P0200
- Most likelyShared injector supply open (fuse, relay, harness connector)
- PossibleSeparate injector power stage or its wiring faulty (diesel)
- Less likelyDriver stage in the engine module faulty
- Less likelyGround fault of the module or power stage
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0200 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 00 | The exact fault in that area. |
What to do next
- Note P0200 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0200
What does P0200 mean?
P0200 means "Injector Circuit/Open". P0200 is the injector circuit fault without a cylinder assignment. It is a generic code, so it means the same on every make.
Is it safe to drive with P0200?
Drive gently and only to a workshop. With P0200 the car can go into limp mode (reduced power) to protect itself.
Will P0200 fail an emissions test?
Yes, it can. P0200 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0200 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0200 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
